Real estate major Supertech on Wednesday filed a special leave petition in the Supreme Court against the Allahabad high court's order to demolish two residential towers in Noida's Sector 93A for flouting building norms.NOIDA: The RWA federation has, in a letter to Noida Authority chairman Rama Raman, demanded construction of boundary walls in residential sectors across Noida to prevent crime.

"In the absence of boundary walls around sectors, the security of the residents is being adversely affected. We've requested CEO Raman to look into the matter," said N P Singh, president of Federation of Noida Residents Welfare Associations (FONRWA).

According to Singh, most of the residential sectors can be accessed through multiple gates.

"Despite RWAs installing CCTV cameras in their sectors, they are unable to stop petty crimes including chain-snatching, car theft and burglaries," he said, "Since there are multiple gates, criminals can not only enter the sector easily but are also able to escape easily."

Certain sectors, including 72, 51, 52, 11 and 12, have villages adjacently located to them. "Movement of unverified (by local police) youths from these villages, mostly working as house helps or labourers, also causes a security hazard," said A N Dhawan, secretary general, FONRWA.

Similar crimes are also witnessed in industrial sectors. "Several cases of burglaries and car thefts have occurred in the last few months owing to lack of adequate police patrolling as well as open access to industrial sectors with no checkpoints. Goods worth thousands have been stolen in the past. A designated boundary wall will help tackle such petty crimes," said Vipin Malhan, president of Noida Entrepreneurs Association (NEA).

Demanding the construction of boundary walls on priority basis for security in residential sectors and their segregation from adjacent villages, the RWA federation urged Raman to issue necessary directions.
